Dax Name Meaning
English: patronymic from Dack. Possibly an Americanized spelling of German Dachs, from Middle High German dahs ‘badger’; hence a nickname for someone who hunted badgers or was thought to resemble the animal. French: habitational name, either from Dax in Landes or (with fused preposition d(e)) from Ax-les-Thermes in Ariège.
